Abstract

Two novel thioarsenates, namely (1,2-pdaH₂)_0.5As₅S₈ (1) (1,2-pda = 1,2-propanediamine) and (NH₄)₂As₈S₁₃ (2) were successfully synthesized through the pH-induced solvothermal methods. 1 is the first three-dimensional chalcogenidoarsenate and 2 features a lamellar structure. The optical properties and thermal stabilities have also been studied.
